Abstract

Úkolem je vyvinout šnekový kompresor (100), který obsahuje vstřikovací potrubí (31a), které může zajišťovat rychlý únik přetlakového chladiva v celém procesu od okamžiku bezprostředně po dokončení sání do výtlaku chladiva, přičemž může zabránit snížení spolehlivosti v důsledku přetlaku. Šnekový kompresor (100) obsahuje alespoň jeden vstřikovací otvor (1f), propojený se vstřikovacím potrubím (31a) pro využití při přivádění chladiva do kompresní komory (20) během komprese, a odlehčovací otvor (1h) pro zabránění přetlaku pro zajištění úniku přetlakového chladiva z kompresní komory (20) ven z kompresní komory (20). Odlehčovací otvor (1h) pro zabránění přetlaku je umístěn v pevném šneku (1) a je propojen s kompresní komorou (20) během celého procesu od dokončení sání do výtlaku v kompresní komoře (20). Odlehčovací otvor pro zabránění nárůstu abnormálního tlaku pro zajištění úniku přetlakového chladiva z kompresní komory (20) ven z kompresní komory (20) je umístěn ve vstřikovacím potrubí (31a).It is an object of the present invention to provide a screw compressor (100) that includes an injection line (31a) that can provide rapid leakage of pressurized refrigerant throughout the process from immediately after completion of suction to refrigerant discharge, while avoiding overpressure reliability. The screw compressor (100) includes at least one injection port (1f) communicating with the injection line (31a) for use in supplying refrigerant to the compression chamber (20) during compression, and a relief port (1h) to prevent overpressure to provide a leak of pressurized refrigerant from the compression chamber (20) out of the compression chamber (20). The overpressure relief opening (1h) is located in the fixed screw (1) and is connected to the compression chamber (20) during the entire process from the completion of suction to discharge in the compression chamber (20). A relief opening to prevent the build-up of abnormal pressure to ensure the release of pressurized refrigerant from the compression chamber (20) out of the compression chamber (20) is located in the injection line (31a).
